Important Notice:No CHANGE in NPTEL Exam Schedule for April 2024

Dear Student,

We wanted to take a moment to address an important matter regarding the upcoming election dates and their potential impact on your exam schedule.

• None of the election dates clash with scheduled exam dates. If we schedule additional dates, we will ensure they again do not clash with elections in your state. 
• Hence this is to confirm that there will be no changes to the exam dates and they are the same as previously scheduled. We may have exams in some cities on April 19 and April 26 depending on seat availability on scheduled dates. But again this will be done ensuring we don't conduct exams on election dates in your state. 
• Your academic progress and success remain our top priority, and we are committed to maintaining the integrity of the examination process.
• We have more than 6 lakh learners registered for April exams and logistics has been a huge challenge. We understand that some of you may need to travel to your native cities to participate in the voting process. Please remember that you selected your exam cities during registration, and it is crucial that you return to these cities to take your exams as scheduled. Since hall ticket and center allocation is under process, exam cities selected by you during exam registration cannot be changed now. 

Hence we kindly request that you make the necessary arrangements to ensure you can both exercise your right to vote and fulfill your academic obligations.

Warm Regards,

NPTEL Team.
